:E j'JR.A HERREN WINOW VENTILATOR Filed Oct. 9, 1928 l Il Patented Feb.Y 25', 1930 UNITED STATES EARL R. HERREN, OF LOB-AIN, OHIO WINDOW `vrzivtirtnfron Applicationy led October 9, 1928. Serial No. 311,344.

This invention relates to a ventilatorl and has for its primary object to provide a ventilator which may be removably positioned in a Window to permit admittance of air without admitting insects or dirt or dust.

Another object of the invention is to provide a removablewindow ventilator which may be'adjusted to different types and sizes of windows.

A still'further obj ect of the invention is to provide an adjustable windo-w ventilator having a screen or curtain which may be used to regulate the admittance of air through the ventilator.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modications mark no material departure from the salient features of the invention as expressed in the appended claim.

In the drawing j Figure l is a top plan view of the ventilator embodying the present invention;

Figure 2 is a front elevational view of o-ne end of the ventilator; 'l

Figure 8 is a transverse section taken on the line 3-3 of Figure l; l Figure 4 is a section taken on the line 4 4 of Figure y2.y f y Referring to the drawing in detail, the numeral 1 indicates generally the ventilator embodying the present invention, the same being formed in two sections, each of which is in- 40 dicated by the numeral 2. As shown, each of the sections is relatively long and comprises a relatively flat casing 3 open along one longitudinal edge as indicated at 4 and having its opposite edge portion turned to provide the upwardly directed section 5, the longitudinal edge of which is open throughout as indicated at 6. y

The inner edges of the casing 3 are rolled as indicated at 7 and the inner end of each is open, one of the open ends of one casing telcscoping into theI .adjacent open end of the other casing, thus making the entire ventilator structure longitudinally adjustable.

A screen of relatively fine mesh is secured over the inner open edge t of the casing as indicated at 8 which prevents the ent-rance of insects or dust and leaves. At the open outer edge, each of the upturned portions 5 is providedV at its outer end with a reel 9 upon which is wound a cloth curtain or screen 10. The sidewalls of the casing adjacent the open outer edge 6 are provided With a longitudinally extending series of apertures 11 into which may be engaged suitable fastening dcvices carried at the opposite edges of the curtains adjacent the free ends of the same so that these curtains maj7 be adj ustably secured in partly drawn out condition to regulate the entrance of air into the ventilator structure.

Theinner wall of the upturned portion 5 of each of the sections of the ventilator` structure is provided witha series of apertures 12 thro-ugh certain alined ones of which a suitable securing member such as a bolt or lthe like (not sho-wn) may be passed to niaintain ythe sections in the proper relation after the same have been adj usted to lit the ventilator to a particular Window.

As shown when the. present ventilator den vice is in position, the horizontal portions of the casings 3 rest upon the window sill and the overlying window sash is lowered to rest upon the top of the casing, the upturned portions 5 of the sections being positioned eXte-k riorly of the window.

Frein the foregoing, it will be readily seen that the ventilator herein described may be economicallyv constructed from pressed metal and the construction of the same is such that it may be readily employed in any window opening and will effectively prevent the entrance of undesirable matter while at the Vsame time allowing free entrance of air into the room.

Having thus described my invention what I claim is A window ventilator comprising an elongated hollow body formed of a pair of telescopically associated portions, said body being of substantially L-shaped cross sectional 13@ design and open along each longitudinal edge, a screen body closing one longitudinal edge7 reels arranged in the ends of the body adjacent the other longitudinal edge, a flexible strip Wound upon each of said reels and adapted to be drawn therefrom longitudinally of the adjacent open edge to close the same. and alpin membe extending tiansversely of the free end of each flexible stripy adapted to have its ends positioned in apertures formed longtudinall 1 of the opposed Walls of the body foi1 maintaining the flexible strip in adj usted position.

In testimony Wlieieof I hereunto aIiX my signature.
